Robbie Williams is backing singer Rylan Clark to take The X Factor's top prize.
Robbie is set to appear on the TV talent contest this weekend offering masterclass help to the remaining contestants, but Rylan has already won over the star.
During the show, Robbie says he is a big fan and then speaks directly to X Factor judge and fellow Take That member Gary Barlow: "Gaz, I don't know what this young man has done to offend you so much.
"And I don't understand how you are missing the obvious brilliance and talent of Rylan, but I am not. I am strictly Team Rylan all the way."
A source told The Mirror that Gary and Robbie have been texting each other about the show, with very different views: "Gary and Robbie are at logger-heads when it comes to Rylan. Robbie has lavished a lot of his time on him - more so than anyone else. Let's hope they are still talking on Sunday night."
This weekend's shows will also see Gary confronting his demons as he has asked contestant Kye Sones to perform Robbie's solo track Let Me Entertain You.
Gary will explain on the programme how the song reminds him of the time when Robbie's career was going from strength to strength, and how incredibly jealous he was of his friend's success.
